Harsh 3-2 Shift Maneuver At 17-20 MPH:

1985-1/2 - 1986 Cutlass Ciera/Cruiser, Cutlass Supreme, Eighty Eight, Ninety Eight, And Toronado/Trofeo

A 3-2 shift maneuver is obtained by allowing the vehicle to coast down to 17-20 mph (with closed or zero throttle) and then stepping into the throttle to obtain a 3-2 shift.

At start of production (SOP) 1987, an orifice pipe was added between the 1-2 servo release cover plate and the 3-2 coast down valve to allow a smoother second gear apply (Figure 5). The four new parts installed as a set will service certain past model transaxles with a harsh 3-2 shift maneuver condition.


If the new pump body assembly has a "one terminal" 3rd clutch switch, remove it and replace with the "two terminal" 3rd clutch switch from the original pump body assembly.

When servicing a transaxle for the above described condition in designated high altitude areas , also install the 3-2 control valve spring package described in Section II of this bulletin.

Also ensure the 3-2 control valve and 1-2 servo control valve move freely in their bores.
